Spray-applied cell therapy with human allogeneic fibroblasts and keratinocytes for the treatment of chronic venous leg ulcers: a phase 2, multicentre, double-blind, randomised, placebo-controlled trial  Prof Robert S Kirsner, MD, Prof William A Marston, MD, Prof Robert J Snyder, DPM, Tommy D Lee, MSHS, D Innes Cargill, PhD, Dr Herbert B Slade, MD  The Lancet  Volume 380, Issue 9846, Pages (September 2012) DOI: /S (12) Copyright © 2012 Elsevier Ltd Terms and Conditions

2 Figure 1 Trial profile Initial screen failures were mostly attributable to non-qualifying wound size, failure to confirm the diagnosis with duplex doppler ultrasonography, and low serum pre-albumin concentration. ITT=intention-to-treat. *Voluntary discontinuation. †Excluding one patient who died of unrelated causes before starting study treatment.

4 Figure 3 Cox proportional hazards analysis of wound healing
The Cox proportional hazards model incorporates a comparison of healed versus open wounds across treatment groups at each of the weekly trial visits, with censoring of missing data. The HR is the likelihood of healing at any given point in time, by group, relative to the vehicle control group. CIs show the range of potential values. HR=hazard ratio.
